Figure 10.17 
Oligosaccharides attached to erythropoietin. Erythropoietin has oligosaccharides linked to three asparagine residues and one serine residue. The structures shown are approximately to scale. The carbohydrate structures represented in the amino acid residues are depicted symbolically by employing a scheme (shown in the key, which also applies to Figures 10.16, 10.23, and 10.24) that is becoming widely used.
